Alpha Orthopedics & Sports Medicine Celebrates 10 Years of Caring

Alpha Orthopedics & Sports Medicine is celebrating its 10th year of caring for the orthopedic needs of our community. Over the years our community served has grown from the McKinney area to include Grayson county and southern Oklahoma. It is because of our friendly northern neighbors that we decided to open an office in Sherman, Texas. We are excited to announce that we saw our first Sherman patient on March 18th at our beautiful new office.

In order to provide full-time orthopedic care to the Texoma community, we are very excited to introduce Duncan McKellar, Jr., MD. Dr. McKellar is an experienced orthopedic surgeon based at our new Sherman, Texas location. Dr. McKellar completed his training at the University of Arizona in 1990 under the tutelage of Dr. Robert Volz, one of the early innovators of joint replacement surgery. For the past 25 years, he has practiced general orthopedics with an emphasis on hip and knee replacements and revisions. He has served in multiple hospital leadership roles including director of Joint Replacement Programs, Chief of Surgery, and Chief of Staff with a career long emphasis on quality and standardization of outcomes in joint replacement surgery.
